Description:
Using a 40mm Plossl at 50X, this globular cluster appears
about 10' in diameter with a large, bright nucleus. Many
stars are resolved.
Increasing the magnificaton to 100X by inserting a 2X Barlow
to darken the background brings out the resolved members so
they appear as jewels sprinkled evenly around the center.
A nice GC.
